I recently purchased AffinityPhoto and now making my way through the AffinityPhoto Workbook ( http://a.co/d/bmZJaJH ).
While the Workbook examples are easy to follow, the Workbook doesn't explain the "when" and "why" behind the steps taken, and I haven't (yet) found a basic explanation of the impact of the various adjustments, filters and such within AffinityPhoto. Consequently, I don't have a framework to guide me through what feature(s) to use based on typical issues encountered in the RAW file.
Does a basic tutorial or guide exist that explains what AffinityPhoto is "doing" through its features to the RAW format? Would a generic book on digital photography answer these kinds of questions (e.g. http://a.co/d/gRrCBe3 ), or does one learn how to image edit based primarily on trial-and error?
